Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for a synthetic resin siding material used as an outer wall material of a building such as a house, and a method of installing the same.

[0002]

2. Description of the Related Art Conventionally, ceramic or metal siding materials have been known as exterior wall materials for buildings such as houses.

[0003] Ceramic siding materials have a profound feeling,
Has excellent features. However, when a heavy ceramic siding material is applied to an existing wall or the like of a building, a heavy load is applied to the existing wall or the like. Further, even in the case of construction, waterproofness cannot be maintained unless a sealing material is used in the vicinity of the opening such as a window or the joint with the accessory. In several years, this sealing material tends to be thin and cracked and easily deteriorate, and rainwater enters from the cracks and the like, causing rain leakage and corrosion of the base material. Further, in a cold region, snow melting water invades, and the freezing and swelling of the siding material is repeated due to the change in temperature, which may cause a serious problem of so-called frost damage.

In order to improve the shape processing, metal-based siding materials are made thinner and made lighter by providing rigidity by backing a foam material, and consideration is given to construction. However, even with this metal-based siding material, the opening portion of the window and the joint with the accessory require a sealing treatment to maintain waterproofness, so that the waterproofing durability is the same as the ceramic siding. I can't expect it. Furthermore, in this metal siding material,
There is also a drawback that the waterproofness cannot be ensured unless the ventilation layer is provided by installing the body edge on the base.

[0005] The surface of these ceramic siding materials and metal siding materials is painted at the time of factory production, but the durability of the painted layer is not so long.

Therefore, synthetic resin siding materials are known to overcome the disadvantages of the ceramic and metal siding materials. This synthetic resin siding material has recently begun to be used in Japan and has a thickness of 9.0.
It is composed of one or two or more layers of synthetic resin plates of about mm to 1.1 mm. Since it is made of a synthetic resin and a sealing agent is not applied to the joint, it has many advantages such as excellent weather resistance, salt damage and freezing damage, good rain fighting, and excellent waterproofness.

[0007]

However, since the synthetic resin siding material has a property of expanding and shrinking due to heat as a property of the synthetic resin as compared with the inorganic siding material, it is difficult to fix the siding material directly to the base material. It is necessary to provide a space for thermal expansion and thermal contraction of the synthetic resin siding material. If such a space is not secured, the siding material may be deformed due to expansion and contraction, or a gap may be generated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a synthetic resin siding that can effectively eliminate deformation and gaps due to thermal expansion and contraction while facilitating workability while utilizing the excellent performance of synthetic resin siding. An object of the present invention is to provide a fixture for a siding material and a method for applying the same.

[0009]

In order to achieve the above-mentioned object, a fixture for a siding material made of synthetic resin according to the present invention is a fixture for attaching a siding material to a base material. An attachment main body block attached to the surface at a predetermined interval, and a holding portion formed on the attachment main body block, for coupling and holding an upper end attachment portion of the siding material slidably in a horizontal direction with respect to the base material. Having.

In the method for applying a siding material according to the present invention, the step of holding the upper end mounting portion of the siding material on the surface of the base material so that the siding material is slidably connected and held in the horizontal direction with respect to the base material. And lower end hooks formed at the lower end of the other siding material so that the upper end mounting portion of the siding material held on the surface of the base material is hidden. Inserting the lower end hook into the downwardly-facing concave recess formed below the upper end mounting portion; and connecting the upper end mounting portion of the siding material with the lower end hook portion inserted into the hidden concave portion of the bulging portion to the siding material. And holding the base material on the surface of the base material so that the base material is slidably coupled and held in the horizontal direction with respect to the base material.

[0011] A building structure according to the present invention is a building structure in which a synthetic resin siding material is attached via a fixture to a base material formed on the outdoor side of a wall surface of the building. A fixture body block attached to the surface of the base material at predetermined intervals, and the fixture body block is formed on the surface of the base material, and an upper end mounting portion of the siding material is slidable horizontally with respect to the base material. And a holding portion for holding the connection.

The holding portion is not particularly limited as long as it can connect and hold the upper end mounting portion of the siding material slidably in the horizontal direction with respect to the base material. It is preferable that a second fitting portion into which a first fitting portion formed on an upper end mounting portion of the siding material is inserted is formed in the holding portion.

The base material is not particularly limited, and examples thereof include a wooden panel, a metal panel, a plastic board, a gypsum board, and a foamed concrete panel.

[0014] The material of the fixture is not particularly limited as long as it has a strength enough to maintain its form.
Examples thereof include plastic, rubber, metal, fiber, and inorganic substance.

The fixture according to the present invention is most effective when it is applied to a siding material made of synthetic resin. As the synthetic resin constituting the siding material, usually, a thermoplastic resin such as vinyl chloride resin, polypropylene resin, polyethylene resin, polymethyl methacrylate resin, polycarbonate resin, ABS resin, fiber reinforced unsaturated polyester resin, epoxy resin, etc. A thermosetting resin or the like is used, but is not limited to the synthetic resins listed here, and may be any type of synthetic resin. By composing the siding material with synthetic resin,
The appearance of a building such as a house can be kept clean over a long period of time. For this purpose, a synthetic resin having a high degree of freedom in coloring and shape design at the time of molding, having little deterioration in physical properties over a long period of time, and having self-extinguishing properties is preferable, and a vinyl chloride resin is more preferable. Among them, vinyl chloride resin is excellent in weather resistance such as not being broken by freezing, chemical resistance such as strong against salt damage, acidity and alkalinity, corrosion resistance, impact resistance, workability, etc., and is the most suitable material for siding materials. It is a suitable resin.

The synthetic resin plate constituting the siding material is
It may be a single-layer synthetic resin plate or a multi-layer synthetic resin plate. In the case of a multi-layer structure, it is possible to improve the durability and secure the economic efficiency by forming the surface layer portion from a material having good weather resistance and the base layer portion from a recycled material. For example, a co-extruded two-layer structure using vinyl chloride resin, the base layer is made of a low-cost resin compound mainly composed of recycled materials, and the surface layer is a virgin resin compound with excellent weather resistance. Is economical. In the case of multiple layers,
Both layers may be made of the same resin material. Separation and recycling are facilitated by using the same resin material.

[0017] The molding method of the synthetic resin plate constituting the siding material may be a modified extrusion molding method for vinyl chloride resin,
A method of molding with a forming die via T-die extrusion is preferably used. In the case of using a polyolefin, injection molding is usually used. When FRP is used, compression molding is preferably used. in this way,
Depending on the type of synthetic resin plate that makes up the siding material,
What is necessary is just to employ | adopt the molding method suitable for each.

The size of the siding material is not particularly limited, but usually, in the case of an extruded product, the vertical dimension is 10 mm.
In the case of an injection-molded product having a width of 0 to 400 mm and a width of 1000 to 5000 mm, it is preferable that the length is about 500 to 1000 mm and the width is about 500 to 1500 mm. Also, the thickness of the siding material is not particularly limited, but may be 0.5 to 10
mm is preferable.

The shape of the siding material is not particularly limited, but when the siding material is attached to the base material using a fixture, an air layer is formed between the back surface of the siding material and the base surface, and this air layer is formed. It is preferable that the connection is made in the lateral direction so that the air layer on the back surface of the siding material and the outside air can be replaced. If the siding material has a configuration capable of forming such an air layer, it is not necessary to provide a trunk edge or a connecting spacer, and the waterproof property against a building such as a house can be maintained.

In the present invention, additives such as pigments, processing aids, heat stabilizers, and ultraviolet absorbers are added to the synthetic resin plate constituting the siding material, if necessary.

[0021]

The attachment of the synthetic resin siding material according to the present invention is fixed to the base material, but the siding material is slidably held in the horizontal direction with respect to the base material. For this reason, even if the siding material undergoes thermal expansion or thermal contraction, it can be absorbed, and it is possible to effectively prevent the siding material from being deformed or having a gap. In the present invention, the siding material can be attached without using the rim, so that the construction work is easy, and even a layman can easily perform the work.
